Description

Corrugated steel plate bending machine

[0001] This application claims priority to Chinese patent applications filed on December 20, 2024, with application number 2024231685184 and application number 2024231685752, both entitled "Waveplate Bending Machine". Technical Field

[0002] This application relates to the field of bending machine technology, specifically to a corrugated steel plate bending machine. Background Technology

[0003] Corrugated heat sinks are highly efficient heat dissipation components widely used in electrical equipment such as power transformers, large liquid and gas containers, and industrial equipment. They effectively dissipate heat, maintain the normal operating temperature of the equipment, and improve its stability and lifespan. For example, they can be used in products such as transformers, installed on the outer surface of the transformer for heat dissipation.

[0004] Corrugated heat sinks utilize metal corrugated heat dissipation technology. Traditional corrugated heat sinks are formed by bending and extruding carbon steel plates. Corrugated heat sink products are manufactured by pressing corrugations onto the steel plate.

[0005] Because bending and extrusion molding require significant forces, the high-load components, such as bending and forming, are designed to be hydraulically driven. High-pressure hydraulic cylinders push the relevant mechanical molds to complete bending, clamping, and extrusion molding actions. Summary of the Invention

[0018] In one embodiment, the lengths of the first link and the second link are approximately equal, such that the adapter block is located approximately in the middle between the first end clamping mechanism and the moving trolley; thereby, the bending mechanism thereon can be controlled to be located approximately in the middle position, which facilitates the positioning of the bending mechanism without the need for additional power to push the bending mechanism to this middle position.

Detailed Implementation

[0041] The technical solutions of this application are described in detail below with reference to specific embodiments. However, it should be understood that, without further description, the elements, structures and features in one embodiment can also be beneficially incorporated into other embodiments.

[0042] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0043] In the description of this application, it should be understood that the terms "upper", "lower", "bottom", "inner", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in Figure 1, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0044] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0045] In existing technologies, bending machines utilize hydraulic drive systems. These systems primarily consist of components such as oil tanks, oil pumps, oil pipes, hydraulic valves, and cylinders, resulting in complex structures and inconvenient maintenance. Specifically: 1. Seals and proportional valves in high-pressure hydraulic systems are consumable parts requiring regular inspection and replacement; improper maintenance can lead to equipment failure. 2. The equipment requires a hydraulic pump station to heat the hydraulic oil, and a cooling system to lower the overheated oil, increasing energy consumption. 3. Hydraulic oil needs regular replacement, increasing operating costs; and hydraulic oil is typically mineral oil, which is not environmentally friendly. 4. The hydraulic system is complex, demanding high skill levels from maintenance personnel. Furthermore, existing hydraulic systems are laid out along the conveyor track, occupying a significant area.

[0046] To address at least some of the problems existing in the prior art, this embodiment provides a corrugated steel plate bending machine for bending and extruding steel plates to form corrugated steel plates, which facilitates subsequent welding.

[0047] Referring to Figures 1 and 2, the corrugated steel plate bending machine (hereinafter referred to as the bending machine) includes a frame 1, on which a conveying track 2 is provided for conveying the steel plate to be bent. The conveying track 2 can be connected to a power drive mechanism (not shown in the figures) for driving the conveying track 2 to convey the steel plate forward (shown as right to left in Figures 1 and 2). In some embodiments, a drive roller type conveying track can be used, and the specific form is not limited, as is well known to those skilled in the art.

[0048] In one embodiment, the bending machine further includes a feeding mechanism 3 for feeding the steel plate to be bent into the conveying track 2. The structure of the feeding mechanism 3 is not within the scope of this application and is not limited thereto.

[0049] To ensure stable bending, the steel plate located on the conveyor track 2 needs to be pressed tightly. The pressing of the steel plate is accomplished by the cooperation of the first end pressing mechanism 4 and the second end pressing mechanism 100. The two sets of pressing mechanisms are installed at intervals on the frame 1, and are used to press the steel plate at the first end position and the second end position, respectively.

[0050] In some embodiments, the second end clamping mechanism 100 is located on the side closer to the feeding mechanism 3, and the first end clamping mechanism 4 is arranged on the side relatively away from the feeding mechanism 3 in the conveying direction of the conveying track 2.

[0051] The first-end clamping mechanism 4 is a fixed structure and cannot move relative to the frame 1. It includes a first clamping mold 402 that can move in the direction of the vertical conveying track 2, used to clamp the steel plate at the first end position. Referring to Figure 3, the first-end clamping mechanism 4 includes a vertical mounting frame 401 arranged in the direction of the vertical conveying track 2, and a first clamping mold 402 mounted on the vertical mounting frame 401. The vertical mounting frame 401 includes two spaced apart ones, and a second track is provided on opposite sides of the two vertical mounting frames 401. The first clamping mold 402 is mounted on the second track and can move up and down along the second track. When moving downwards, it can move in the direction of the conveying track 2 to clamp the steel plate.

[0052] In one embodiment, to drive the first pressing mold 402 to move, a first motor 403, a first lead screw 404, and a drive arm 405 can be designed. The two ends of the drive arm 405 are respectively connected to the first lead screw 404 and the first pressing mold 402. The power output end of the first motor 403 is connected to the first lead screw 404, driving the first lead screw 404 to rotate, which in turn drives the drive arm 405 to move, thus driving the first pressing mold 402 to move up and down.

[0053] As shown in Figures 5-7, the second end clamping mechanism 100 includes a traveling rail 9 arranged along the direction of the parallel conveying track 2, a movable trolley 10 slidably mounted on the traveling rail 9, and a second clamping mold mounted on the movable trolley 10. The first and second clamping molds are arranged opposite to each other to clamp the steel plates from both ends respectively.

[0054] In one embodiment, as shown in FIG10, a first slider 1001 is provided at the bottom of the mobile trolley 10, and the mobile trolley 10 is mounted on the travel rail 9 via the first slider 1001.

[0055] As shown in Figure 8, the bending mechanism 103 is disposed between the first end pressing mechanism 4 and the second end pressing mechanism 100.

[0056] Unlike the first end clamping mechanism 4, the second end clamping mechanism 100 is designed to be movable, facilitating adjustment of its clamping position and enabling bending of the steel plate at different locations. Once the steel plate is fixed between the two clamping mechanisms and the bending mechanism 103 is activated, the bending operation on the steel plate is completed.

[0057] In one embodiment, a motion drive structure for the mobile trolley 10 is also designed.

[0058] As shown in Figure 5-8, the guide arm 12 is installed on the frame 1 in a direction perpendicular to the conveying track 2, and a guide rail 1201 is provided along the height direction of the guide arm 12.

[0059] The first end of the connecting arm 13 is connected to the moving trolley 10, and the opposite second end is connected to the guide rail arm 12;

[0060] The first end of the connecting arm 13 is axially connected to the moving trolley 10, and the second end of the connecting arm 13 is connected to a second slider 14. The second slider 14 is mounted on the guide rail 1201. The axial connection described in this application can also be understood as a hinge connection, that is, the two connected parts can rotate relative to each other.

[0061] The second slider 14 can move up and down within the guide rail 1201. When the second slider 14 moves downward along the guide rail 1201, it drives the moving trolley 10 to move closer to the first end pressing mechanism 4. When the second slider 14 moves upward along the guide rail 1201, it drives the moving trolley 10 to move away from the first end pressing mechanism 4. The up and down movement of the guide rail 1201 drives the horizontal movement of the moving trolley 10, thus making reasonable use of the longitudinal space and saving space for horizontal movement.

[0062] To drive the second slider 14 to move, a second drive mechanism can be designed. The second drive mechanism is connected to the second slider 14 and, upon startup, drives the second slider 14 to move up and down along the guide rail 1201. The second drive mechanism preferably adopts a second motor 19, the power output end of which is connected to a second lead screw 20, which is connected to the second slider 14.

[0063] In one embodiment, the guide arm 12 includes a first guide arm 1202 and a second guide arm 1203 spaced apart in the width direction of the conveying track 2; the connecting arm 13 includes a first connecting arm 1301 and a second connecting arm 1302, which are respectively connected to both ends of the moving trolley 10 in the width direction. The first connecting arm 1301 is connected to the first guide arm 1202 via a first sub-slider 1401, and the second connecting arm 1302 is connected to the second guide arm 1203 via a second sub-slider 1402. That is, the second slider 14 includes a first sub-slider 1401 and a second sub-slider 1402.

[0064] The double-sided guide rail arm structure ensures the stability of the moving trolley 10. Correspondingly, the first sub-slider 1401 and the second sub-slider 1402 are each connected to an independent second motor 19. The power output end of each second motor 19 is connected to a second lead screw 20, and each second lead screw 20 is connected to the corresponding first sub-slider 1401 or second sub-slider 1402. The two second motors 19 are driven synchronously, causing the first sub-slider 1401 and the second sub-slider 1402 to rise or fall synchronously.

[0065] To ensure the synchronization of the two second slider movements, a synchronization structure for the second sliders is further designed. Specifically, as shown in Figure 6, the first sub-slider 1401 is connected to the first positioning arm 2101, which extends towards the second sub-slider 1402; the second sub-slider 1402 is connected to the second positioning arm 2102, which extends towards the first sub-slider 1401; a sensor 101 is provided on the opposite side of the first and second positioning arms 2101 (obscured and not visible in Figure 6, i.e., the sensor 101 is located between the two arms), which is used to detect the alignment information of the first and second positioning arms 1401 and 1402. As shown in Figure 11, the bending machine also includes a controller 102, which is connected to the sensor 101 and two second motors 19. When the sensor feedback indicates a positional deviation between the two second sliders, the synchronization of the two second slider movements can be adjusted by adjusting the action of the corresponding second motor 19. If the movement positions of the two second sliders deviate significantly, the second motor 19 on one or both sides can be stopped immediately to protect the equipment structure from damage.

[0066] In an optional embodiment, the sensor 101 is a photoelectric sensor, including a transmitter and a receiver disposed opposite to each other. The transmitter is located on one of the first positioning arm 2101 and the second positioning arm 2102, and the receiver is located on the other. When the receiver can receive a signal from the transmitter, it indicates that the two arms 2101 and 2102 are aligned; otherwise, it indicates that a positional deviation has occurred between them. The second motor 10 is then stopped immediately to prevent further positional deviation and thus protect the equipment. The controller 102 includes a processor and a memory, and is capable of controlling the bending machine. The processor is, for example, a CPU, PLC, industrial computer, or other computer hardware. Programs that can perform corresponding functions are stored in the memory, and the processor executes these programs to achieve the various functions described above. This is well known to those skilled in the art.

[0067] Through the aforementioned driving structure of the mobile trolley 10, and the driving structures of the first sub-slider 1401 and the second sub-slider 1402, the electric motor driving structure replaces the hydraulic driving structure, simplifying the structure of the driving system and improving production efficiency. Furthermore, by converting the vertical driving force into the horizontal driving force of the mobile trolley 10, under the same force magnitude, the vertical pushing force can be converted into a larger force on the mobile trolley 10, resulting in a more stable pushing effect.

[0068] In one embodiment, as shown in Figures 6 and 7, the second end clamping mechanism 100 (or the second clamping mold) includes a cylinder 15 and a clamping plate 16. The cylinder 15 is mounted on the moving trolley 10, and the clamping plate 16 is connected to the power output end of the cylinder 15. The extension and retraction direction of the power output end of the cylinder 15 is towards the conveying track 2. Here, "towards the conveying track 2" can be a horizontal direction perpendicular to the conveying track 2, or it can be a direction at an angle to the conveying track 2. It is necessary for the power extension and retraction end of the cylinder 15 to move in the direction of the conveying track 2, and the clamping plate 16 to clamp the steel plate on the conveying track 2.

[0069] In one embodiment, the cylinders 15 include a plurality of cylinders arranged along the width direction of the pressure plate 16. The power output end of each cylinder 15 is connected to the pressure plate 16, and each cylinder 15 is connected to a cylinder drive mechanism. The cylinders 15 are driven synchronously. When the cylinder 15 is activated, the pressure plate 16 is driven to press the steel plate.

[0070] In one embodiment, the bending machine further includes a linkage mechanism 11. Referring to Figures 5, 6, and 8, the linkage mechanism 11 includes a first link 1101, a second link 1102, and a transition block 1103; the first end of the first link 1101 is axially connected to the transition block 1103, and the opposite second end is axially connected to the moving trolley 10; the first end of the second link 1102 is axially connected to the transition block 1103, and the opposite second end is axially connected to the frame 1, or to the first end pressing mechanism 4. The bending mechanism 103 is connected to the transition block 1103. When the moving trolley 10 moves, it will drive the first link 1101 to move, which in turn drives the second link 1102 to move. When the second link 1102 moves, it can synchronously drive the bending mechanism 103 to move.

[0071] Referring to Figure 4, the bending mechanism 103 includes a core plate 5 and a third drive mechanism. The core plate 5 is a rectangular flat plate, and the surface of the core plate 5 is set perpendicular to the conveying track 2 (set along the vertical direction in the figure); the length direction of the core plate 5 is set parallel to the width direction of the conveying track 2, and the core plate 5 is connected to the third drive mechanism to drive the core plate to move in the direction perpendicular to the conveying track 2.

[0072] After the first and second end clamping mechanisms clamp the steel plate, the third drive mechanism is activated to drive the core plate 5 to move up and down. In the direction shown in Figure 4, during the process of corrugating the steel plate, the core plate 5 is driven to move upward, contact the steel plate on the conveying track 2, apply force to the steel plate, and complete the bending operation; after the corrugating action is completed, the core plate 5 is driven to move downward and detach from the steel plate.

[0073] In one embodiment, the specific installation configuration of the core plate 5 is shown in Figures 4, 8, and 10. The bending mechanism 103 also includes a core plate base 6 and a core plate support 22. The height direction of the base 6 is perpendicular to the direction of the conveying track 2. The core plate 5 is inserted into the upper part of the support 22 and fixed by a fastener. The core plate 5 is connected to a third drive mechanism to drive the core plate 5 to move up and down. The length direction of the core plate 5 is parallel to the width direction of the conveying track 10. A core plate 5 of a suitable size can be replaced according to the bending requirements of different corrugated sheets. For protection, a protective plate 23 can be further installed on the outside of the support 22. The base 6 is mounted on the adapter block 1103 and can follow its movement.

[0074] In one embodiment, the structure of the first link 1101, the second link 1102, and the adapter block 1103 is divided into two sets, located at two points along the width of the conveying track 2. That is, there are two linkage mechanisms 11, located at both ends along the width of the conveying track 2, as shown in Figure 6.

[0075] To stabilize the mating structure between the core plate 5 and the base 6, the base 6 is divided into a first base rail 601 and a second base rail 602 along the width direction of the conveying track 2. A base plate 605 is located between the first and second base rails 601 and 602. Two clamping plates 606 are installed on the top of the base plate 605, forming a clamping gap 607 between the clamping plates 606. The core plate 5 passes through the clamping gap 607 to achieve auxiliary fixation of the core plate 5.

[0076] The outer walls of the first base rail 601 and the second base rail 602 are respectively provided with motion rails 604 perpendicular to the conveying track direction. Each adapter block 1103 is installed on a corresponding motion rail 604 of the base rail and can move along the motion rail 604. A third slider 603 is provided on both the first base rail 601 and the second base rail 602. The third slider 603 can be installed on the traveling rail 9 to move within the traveling rail 9. Therefore, as shown in Figure 8, both the third slider 603 and the moving trolley 10 can move on the traveling rail 9, and the third slider 603 is located between the first end pressing mechanism 4 and the moving trolley 10, thereby placing the core plate 5 between the first end and the second end pressing mechanisms.

[0077] In one embodiment, the third drive mechanism includes a third motor 7 and a third lead screw 8. The power output end of the third motor 7 is connected to the third lead screw 8, and the third lead screw 8 is connected to the core plate 5. It can drive the bracket 22 to move along the vertical conveying track 2, thereby driving the core plate 5 to move up and down. Compared with the hydraulic drive structure, using the third motor 7 and the third lead screw 8 as the drive structure for the core plate 5 can greatly simplify the complexity of the drive system and ensure the stability of the core plate 5.

[0078] In one embodiment, the core plate 5 is disposed below the conveyor track 2. This structure can utilize the space below the frame 1, improving the overall compactness of the bending machine structure.

[0079] During the bending process, the position of the base 6 needs to be adjusted to change the position of the core plate 5 in order to achieve bending at different locations on the steel plate. The mating structure between the base 6 and the traveling rail 9 limits the direction of movement of the base.

[0080] The working process of the corrugated steel plate bending machine provided in this embodiment is as follows.

[0081] The first end clamping mechanism 4 and the second end clamping mechanism 100 simultaneously clamp the steel plate.

[0082] Start the second motor 19 to drive the second slider to move downward along the guide arm 12, thereby pushing the moving trolley 10 to move in the direction of the first end pressing mechanism 4.

[0083] The moving trolley 10 moves, synchronously driving the linkage mechanism 11 of the first link 1101 and the second link 1102 to move, thereby driving the bending mechanism 103 to move towards the first end pressing mechanism 4.

[0084] The core plate 5 is pushed upwards, and the core plate 5 acts on the steel plate, bending the steel plate. During the upward pushing of the core plate 5, the moving trolley 10 is moved simultaneously.

[0085] The first end clamping mechanism 4 and the second end clamping mechanism 100 release their clamping on the steel plate and move the core plate 5 downward.

[0086] The conveyor track 2 moves the steel plate forward, repeatedly presses the steel plate, and performs the embossing operation at the next position.

[0087] As an auxiliary structure, the corrugated steel plate bending machine also includes a front-end cutting mechanism 17 and a folding mechanism 18. This part of the structure belongs to the prior art and will not be described in detail in this application.

[0088] The described embodiments are merely preferred embodiments of this application and are not intended to limit the scope of this application. Any modifications and improvements made by those skilled in the art to the technical solutions of this application without departing from the spirit of this application shall fall within the protection scope defined by the claims of this application.
